This PR: - builds on top of https://github.com/ComposioHQ/composio/pull/4358 - replaces the eleven `Effect.Service` files (fourteen services) with `Context.Tag` classes that export a `<Name>Shape` type and an explicit `static readonly Default` layer built from a `make<Name>` constructor - removes the three `accessors: true` declarations; nothing in `src/` used a generated accessor, and the one test that did now yields the service - builds test doubles with `Service.of({ ... })` instead of `new Service({ ... })`, and types helper parameters with the `Shape` types where the class had been used as a type - passes the normalized argv from `bin.ts` into `runCli` and through `cli-main.ts` instead of mutating `process.argv` and reading it back in five places - documents the service pattern in `ts/packages/cli/AGENTS.md` ## Context Effect v4 replaces `Effect.Service` with `Context.Service`, which generates neither a `.Default` layer nor accessors; with the explicit-layer shape already on v3, the port turns each service into a one-line rename. `Command.runWith` in `effect/unstable/cli` takes user arguments explicitly, so `cli-main.ts` now receives argv rather than re-reading process state. Second of three preparation PRs. ## Validation - `pnpm --filter @composio/cli typecheck`, `validate:boundaries`, and oxlint clean - `pnpm --filter @composio/cli test`: 127 files, 1319 tests pass, 1 skipped
Composio TypeScript workspace
This directory contains the TypeScript half of the Composio SDK monorepo: the core SDK, provider adapters, the CLI, examples, and end-to-end tests. For an overview of Composio itself, start at the root README and docs.composio.dev.
If you just want to use the SDK:
npm install @composio/core
import { Composio } from '@composio/core';
const composio = new Composio({ apiKey: process.env.COMPOSIO_API_KEY });
const session = await composio.create('user_123');
const tools = await session.tools();
See the @composio/core README and the quickstart for the full flow, including provider setup for your agent framework.
Packages
Published packages:
| Package | Description |
|---|---|
@composio/core |
The Composio SDK. Ships its TypeScript source and SDK docs so installed copies are inspectable by coding agents. |
@composio/slim |
Same API as @composio/core without the packaged source and docs; smaller install. |
composio CLI |
Standalone CLI binary: search, execute, and script tools from your shell. |
@composio/* providers |
Adapters that format Composio tools for agent frameworks (OpenAI, Anthropic, Vercel AI SDK, LangChain, and more). See the provider table. |
@composio/experimental |
Experimental integrations, currently the Pi provider. |
@composio/json-schema-to-zod |
JSON Schema to Zod conversion. |
Internal (unpublished) packages: cli-keyring and cli-local-tools support the CLI; ts-builders generates TypeScript source.

Development
Commands run from the repository root. Install the pinned toolchain first:
mise install
pnpm install
Build and verify:
pnpm build:packages # build all TS packages
pnpm typecheck # typecheck all TS packages
pnpm lint:packages # oxlint over ts/packages
pnpm test # package unit tests plus example validation
Runtime E2E suites (require credentials):
pnpm test:e2e:node
pnpm test:e2e:deno
pnpm test:e2e:cloudflare
pnpm test:e2e:cli
Scaffolding:
pnpm create:provider <name> [--agentic] # new provider package
pnpm create:example <name> # new example under ts/examples
